Hi thanks for the reply, I managed to get it sorted though I don't know why I didn't think of it, but I just ran a system restore as the tweak utility made a restore point before running it and it's working fine now I think it was deleting some important files as it did a "junk" file clean and registry clean and I noticed that I saw some important Windows files being deleted as it was cleaning, it's just a dodgy program lol just out of interest, is a mouse refresh rate something to do with optical/laser mice? Even though it is working fine now, is there a way to change the refresh rate of it, for a better pickup or anything? Also the mouse has a thing where it half turns off to save battery after a couple of minutes, with or without the Setpoint drivers, do you know if there is a way to disable this? It's just if I'm playing a game like BF2 and am camping, the mouse takes a second or 2 to get back to itself after being idle, it would be good if I could disable that feature
